Abstract: The present invention transforms the vast amount of existent vehicular travel into an equally-vast alternative energy resource employable for the generation of electricity. This transformation is achieved by means of a novel system which generally includes a momentum-conversion assembly configured to convert available vehicle momentum into operational momentum for an associated momentum-referenced electricity generator. The conversion assembly is accordingly structured to be responsive to the passage along an associated roadway of vehicles having predeterminable roadway-traversal momentum, with a portion of this momentum then being that which is cooperatively applied to the generator. The resulting double utilization of associated energy resources for both vehicle motion and electricity generation constitutes an effective increase in resource conversion efficiency.

Abstract: An air scrubbing and purifying system is provided for effecting removal of combustion products from contaminated air generated by a fire in progress in an enclosed room. The system comprises (a) electrically-powered intake fans for withdrawing contaminated air from the enclosed room, (b) air washing and filtering stations adapted to treat and remove soot, smoke, and other combustion-product gasses from the contaminated air, and (c) electrically-powered discharge fans for impelling the treated air into the enclosed room. The system is actuated and made operational by means of a smoke or fire detector and is powered by integral batteries kept in a charged state by an appropriate trickle charging device. The system is advantageously disposed within a door structure for the enclosed room and may include extendable seal strips at the peripheral surfaces of the door to aid in sealing the enclosed room from adjacent areas.

Abstract: Apparatus is disclosed for quickly delivering a flow or spray of an eyewashing liquid such as water to the eyes of the wearer of a helmet or hard hat. A reservoir of appropriate liquid is formed within the helmet or hard hat. Air pressure is applied to the body of liquid by means of an associated pneumatic priming pump. Conduits communicate between the reservoir and duct members which are positioned to direct the flow of liquid into the eyes of the user. The duct members are opened by the pulling of a string which releases plugs located therein.
